Hi,

Tested musl commit 04983f227238 (make netinet/in.h suppress clashing
definitions from kernel headers) and a patch by Felix Janda
https://lkml.org/lkml/2016/11/11/210 . This fixes arptables and
conntrack-tools for kernels 4.8 and later. For netifd, ebtables and ppp
this fixes the netinet/in.h related issues without reordering of any
headers.
